Arthur, a steampunk laborer, carries Merlin's hidden archmage blood. Demons awaken his holy magic, earning him a spot at the noble-only War Academy. Spoiled Anderson and corrupt Samuel rig deadly trials, frame him as dark spawn, and put his mother on trial to break him. Cornered, Arthur unlocks full archmage power and exposes their plot. With the Abyss seal failing and Lucifer marching, the underdog heads to the citadel for the Divine Throne.
